I have started the worksheet for you. Complete the rest of the terms. Use images that illustrate the terms. You may work with a partner or two and divide up the terms between the group of 2-3 people. You should also work directly with a camera to see these things on the actual digital slr.
Use Pages software to complete the sheet with images. When you have finished the Pages document copy and paste it into a new wiki page called Your Names Digital SLR Worksheet and post it to our wiki. Make sure to insert the images properly and make anything that needs to be a link into one.
Aperture:
The size of the opening in the lens also known as f/stop. (a smaller aperture has a bigger f/stop number--lets in less light) The numbers represent ratios of the lens focal length to opening. The lens focal length is how long the lense is in millimeters. So f/2 is a wider open aperature than f/16 because the numbers are fractions.
Depth of field:
Define and explain depth of field and then find some photographs that show depth of field variance and post them here.
Depth of field determines how much of your shot will be in focus and how clear the background will be.
Shutter Speed:
How long of a period of time the shutter is open.
Noise:
Appears as pixelation or dots all over your photo causing it to look unfocused.
Histogram:
It graphs the range of tone used in a photo from black to white based on the number of pixels.
Burst Mode:
Also called continuous shooting, this mode takes a certain number of pictures per second, usually by just holding down the shutter button.
White Balance:
Light reflects off surfaces making them appear warmer/colder, white balance is used to make colors captured in an image more accurate/closer to their real-life counterparts.
Self timer:
A built-in timer that delays shutter release usually by ten seconds allowing you to join the picture yourself.
Pixels:
The smallest unit of a picture. Usually appears as tiny squares making the image blurry.
Auto Focus vs. Manual Focus: (explain what they are and then explain when you would choose each and why?)
Auto focus is when the camera focuses the shot for you. You would use it when trying to capture a photo quickly or when you need to focus fast-moving object. Manual focus is when you adjust the lenses yourself. You could use it when you have a single object you want to be in focus, such as a tree on a landscape.
AUTO
MANUAL
ISO (international standardization organization):
Measures sensitivity of the image sensor. Lower numbers indicate a lower sensitivity to light and less noise, and higher numbers should be used in darker lighting and when a faster shutter speed is needed but produces more noise.
File Format:
Define each and explain how they differ from each other.
.tiff – Highest quality file format that retains data in layers and does not lose quality when edited. However, it cannot be posted on the web.
.jpeg – The most common file format useable by all programs and computers and can be viewed on the web, whereas a .tiff cannot be posted online. Also, you can choose the level of quality you want to save the image in, but it loses quality each time you edit and save it.
.raw – An unprocessed file type in which the photo is not ready for print or editing. Also, it’s the largest file type meaning it takes a longer time to save and you cannot store as many.
